I think we've already decided we're willing to piss off the BSD folks,
but just in case we haven't I googled around for a more portable way to
do this. It seems argv[0] *may* be better, may not. In any case, this
reminds me that maybe we should start noting things which won't work in
non-linux operating systems.
I also find it comical that adding the argument, and writing the
surface is like 5 lines, and the rest is all finding the damn executable
path :-)
